- a. the response, variable
- b. the factors
- c. the levels of each factor
- d. the number of treatment combinations
- e. the experimental units
- f. the number of observations for each treatment combination

C.15 Hospital Stays. The U.S. National Center for Health Statistics collects data on length of stay in noninstitutional, short-stay hospitals by sex and age. Results are published in Vital and Health Statistics. Independent random samples of Americans were taken to compare the lengths of stay (in days) for males and females in four age groups (15–24 years, 25–34 years, 35–14 years, and 45–64 years). The data are in the following table.

3. To determine what suitable teaching
techniques to use for the students with learning
disorder under the special education program of
a certain school, an IQ exam was administered
to selected students. Out of the 117 students
diagnosed with specific learning disorder, 50

B. Population
C. Sample
D. Variable/s involved (Indicate the IV &
DV if possible)
E. Level of measurement (Variable/s)
4. A professor recorded the scores from prelim
exam as obtained by his students to characterize
their competency on the subject matter being
covered. Among his 8 sections (with 50 students
each), he included 15 students from each class
through systematic sampling. As a result, the
mean score of the selected students is 84 which
can be classified as average.
